PULLLEEEASE!!!!
Give me a break! and all of us a break.
While this machine merits some conversation amongs dishwasher fans, it was nothing revolutionary at all and was probably never sold in large enough numbers to really compete with the major players.
All I can tell you is that GE did make a vast line of commercial cooking products. They had Kettles, Braising pans, fryers and even Microwave ovens which were absolutely huge at the time. The made dishwashers too, from single tanks like the one in the link to multitank units. They made grills for McDonalds that were so rock soild and well designed too. They may actually have been the first company to make computer controlled fryers that surpassed anything on the market and were designed to provide consistent results batch after batch. Even their toasters went from the classic bimetal style timers to an electronic timer that would account for the ambient temperature in the toaster so that you would get toast that looked identical to the slices that came before it as well as after it.
Many of the larger ranges were branded as Hotpoint and the fryers as well.
In 1981, they sold the commercial cooking, dishwasher and water cooler lines to Hobart and Hobart continued with the same designs for years. In fact, Hobart/Vulcan/Wolf all market many items that are basically identical to the stuff GE made. Much of the counter line was eventually sold to APW-Wyott who has continued building those products to the same design and specs as the original GE designs.
The dishwashers were already winding down by the time GE sold it to Hobart and the production just ceased. Therefore, since nothing for them has been made for over 30 years, there would be nothing at all available for them. Anyone who buys that dishwasher will be in for a surprise!
